           Summary: Issue when rendering with 2 contexts to one window
           Product: DRI
           Version: XOrg CVS
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: General
        AssignedTo: dri...@li...
        ReportedBy: ste...@gm...


r200 dri seems to have some issues when an application renders from 2 threads 
to the same window with 2 different contexts.

According to the glXSwapBuffers manpage it is ok to render to one window with 
2 contexts. I have experienced issues with the glDrawBuffer setting when doing 
that. I will attach a small test application which shows the bug.

(sorry if this bug report appeared 2 times - I had a system crash when I filed 
it the first time, I couldn't find the bug, so I assumed it wasn't filed and 
rewrote it)
